Greater Vernon Water (GVW) is switching its water source to conduct some planned maintenance.

The Duteau Creek water source will be turned off the week of March 27 for planned maintenance work. GVW will be providing water to all customers from the Mission Hill Water Treatment Plant supplied by Kalamalka Lake.

Customers regularly receiving Duteau water could notice a change in their water as Kalamalka Lake water is harder and more alkaline.

This may be of interest to customers who have in-home water treatment systems or aquariums.

As an emergency backup supply, the Antwerp Deep Well and Ranch Well No. 1 have are on standby and will only be used if needed. Both the Antwerp Deep Well and Ranch Well No. 1 are approved by Interior Health as emergency potable water use backups and are considered safe as drinking water sources.

The Antwerp Shallow Well that was contaminated in 2010 has been permanently taken off-line and will not be used by GVW as a potable water source.

If the Antwerp Deep Well is used, road signs will be posted in affected areas and the RDNO website will have a map a map outlining impacted customers.

It is anticipated that the work will be completed by March 31, but could be extended if required.
